Been using the headset off and on for a month now and the battery is working as expected. White noise machines and box fans would not drown out the loud noises that kept waking me up. They are still a bit big on me. It is perfect for what I needed and what I was looking for. (Sun dresses, Nike shorts, or jean shorts)They?ve been in the pool, the lake, mud puddles, sand, and everything in between. It fits perfect - almost like it was custom made for the Ridgeline. The ear cups started disintegrating after 3 years and I replaced them. Ich habe jedoch zb on-ears und die klingen um Welten besser. It came with everything needed including the batteries. Bought these for my Mum.
